VOPS0005: Guest virtual machine freezes during the backup

Symptom

The guest virtual machine (VM) freezes during the backup of the VM.

Cause

The Ceph libraries are updated, but the VM process is still using older Ceph libraries.

To determine whether this is issue, perform the following steps:

1. Check the versions of the Ceph libraries that are present on the compute node where the VM is running.

   - /lib64/librbd.so.X.X.X

   - /lib64/librados.so.X.X.X

2. Run the following command to check the Ceph binaries that are loaded by the QEMU process on the compute node where the VM is running.

   # cat /proc/<PID of the Guest VM qemu process>/map_files

   From the output of this process, check the versions of the Ceph libraries (librbd and librados). These libraries should not be marked as deleted.

Resolution

1. Turn off the guest instance.

2. Start instance (Power On the Guest Instance); this will reload the updated Ceph libraries.

3. Run the following command to check the Ceph binaries that are loaded by the QEMU process on the compute node where the VM is running.

   # cat /proc/<PID of the Guest VM qemu process>/map_files

   From the output of this process, check that the updated versions of the Ceph libraries (librbd and librados) are utilized for processing.
